DESCRIPTION
readelf displays information about one or more ELF format object files. The options control what
particular information to display.
elffile... are the object files to be examined. 32-bit and 64-bit ELF files are supported, as are
archives containing ELF files.
This program performs a similar function to objdump but it goes into more detail and it exists
independently of the BFD library, so if there is a bug in BFD then readelf will not be affected.
OPTIONS
The long and short forms of options, shown here as alternatives, are equivalent. At least one option
besides -v or -H must be given.
-a
--all
Equivalent to specifying --file-header, --program-headers, --sections, --symbols, --relocs,
--dynamic, --notes and --version-info.
-h
--file-header
Displays the information contained in the ELF header at the start of the file.
-l
--program-headers
--segments
Displays the information contained in the file's segment headers, if it has any.
-S
--sections
--section-headers
Displays the information contained in the file's section headers, if it has any.
-g
--section-groups
Displays the information contained in the file's section groups, if it has any.
-t
--section-details
Displays the detailed section information. Implies -S.
-s
--symbols
--syms
Displays the entries in symbol table section of the file, if it has one.
-e
--headers
Display all the headers in the file. Equivalent to -h -l -S.
-n
--notes
Displays the contents of the NOTE segments and/or sections, if any.
-r
--relocs
Displays the contents of the file's relocation section, if it has one.
-u
--unwind
Displays the contents of the file's unwind section, if it has one. Only the unwind sections for IA64
ELF files are currently supported.
-d
--dynamic
Displays the contents of the file's dynamic section, if it has one.
-V
--version-info
Displays the contents of the version sections in the file, it they exist.
-A
--arch-specific
Displays architecture-specific information in the file, if there is any.
-D
--use-dynamic
When displaying symbols, this option makes readelf use the symbol table in the file's dynamic
section, rather than the one in the symbols section.
-x <number or name>
--hex-dump=<number or name>
Displays the contents of the indicated section as a hexadecimal dump. A number identifies a
particular section by index in the section table; any other string identifies all sections with that
name in the object file.
-w[liaprmfFsoR]
--debug-dump[=line,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges]
Displays the contents of the debug sections in the file, if any are present. If one of the optional
letters or words follows the switch then only data found in those specific sections will be dumped.
-I
--histogram
Display a histogram of bucket list lengths when displaying the contents of the symbol tables.
-v
--version
Display the version number of readelf.
-W
--wide
Don't break output lines to fit into 80 columns. By default readelf breaks section header and segment
listing lines for 64-bit ELF files, so that they fit into 80 columns. This option causes readelf to
print each section header resp. each segment one a single line, which is far more readable on
terminals wider than 80 columns.
-H
--help
Display the command line options understood by readelf.
@file
Read command-line options from file. The options read are inserted in place of the original @file
option. If file does not exist, or cannot be read, then the option will be treated literally, and
not removed.
Options in file are separated by whitespace. A whitespace character may be included in an option by
surrounding the entire option in either single or double quotes. Any character (including a
backslash) may be included by prefixing the character to be included with a backslash. The file may
itself contain additional @file options; any such options will be processed recursively.
